To all 'whom t may concern.- l

; Beit., known that `1W ILLIAM GEonGn BEA11IE,yof=Nine Elms, ,Londonf England, Engineer, have invented provtements` in Axle-Boxes, if .ments are. fully setforth in the following speci- ,fication, .referencepbeinghad to the accompa-p` .new and useful In1- which` improvef, nying drawings.

My vinvention consists, ,ashereinafter de scribedof apparatus for regulating, the supply of oil in the ax1ebox,and forthis purpose Il xeitheriuternallyor externally to theaxlea rod passing down the cy1inder.p']3 he .lower end of Vthe cylinder is level with the bottom of the axle-box, and thelinside of upperendthrough `which the rod passesis at the proper level of the oil in the box.. The rod is of such length ,that thev piston rests on thelowerendpf the cylinder. In

the side of the cylinder oncor more apertures .cqmmuucatingwth theinterior 0f. the axlebox are formed just above the piston when it Vis resting ou the bottom of the cylinder, and

also one or more apertures of small size at the upper end ofthe cylinder.

`The accompanying drawings illustrate the manner in which I-carry myinventioninto ef-` fect.

'the axle-box be supplied with oil is shown at Fig. l.

ais the cylinder being formed inthe lower part of the axle-box, and'b the piston being fitted to it, andattached to the rod c passing to the upper part of the axle-box, and ending e are oneor ,more holes made at the lower part of the cylinder, and f are one or Vmore holes at the upper part of the cylinder.

When it is desired to ascertain if' there be oil in the axle-box, the knob end d of the piston-rod c is to be raised, and if there be oil in the box it will have passed into the cylinder l l Figurel is a longitudinal section, Fig. 2 is a transversesection,

.through the `lowerl'apertures e,andgwill,be

Iflxtheplugyto the cock to theaxle-box,

and I `make the seating offthe cockmovable onthe plug, which has a passage through,y it leading into the axle-box. YIalso prefer :to place in .the passagethroughtha plug `aspiral spring, and attachn theexternal casing tn itso thatpit (the external casing)is kept. pressed 1 `dniothe plug. `An aperture isgforined in the seatingoncasing' to correspondto the passage and the seatingihasfn.oneside,

in the plug, l a handle, the weight .ofwliicu causes the cock to shut"itseliflitthe,accidently left open.

The construction of thevalve for supplying the axle-box with oil is shown at Figs.` 2, 3, and 4. g is the plug attached to the axle-box, and formed w-itha passage through it, as

`shown in dotted lines at Fig. 2. h isthe casing attached to the plug, either by riveting or by a spring, and has a passage, k, formed through it to correspond to the entrance to the passage through the plug at l. m is the handle on the casing h, the weight of which tends to keep the valve closed.

1 place in the lower part of the Vaxle-box, just above the proper level of the oil, a diaphragm, which may be of thin sheet-iron, or be formed solid with the box, and Imake through the diaphragm one or more apertures, preferably circular, through which I pass the carriers for the lubricating-Wicks. The carriers are hollow, and are formed of tin or thin metal, and pass through the apertures in the diaphragm-plate, which they tit nearly to the bottom of the box, and are attached tothe diaphragm, and extending up through it nearly to the under side ot' the journal. Inside the carriers Iplace the lubricating-Wicks, which I l lmake of a mixture of cotton-wick and worsted,

' ing-wicks are placed is shown at Figs. 1 and 2. n n is the diaphragm, formed in the lower part of the axle-box and above the proper level of the oil, and o o o are the circular metal carriers for the lubricating-wicks, which are passed through passages formed in the diaphragm. p p are the wicks, pressed up against the under side of the axle journal by the action'of the spiral springs, through which the wicks are passed. The carriers are perforated at r r, as shown.

To prevent the oil escaping from the'box, or dust entering, I place round the collar of the journal nearest to the wheel a shield of wood or other suitable material, formed in two parts, onel part resting on the upper side of the journal and' the other part being c arried by a spring resting on the under side of the recess in the axle-box in which the shield is' contained, so that it is pressed up to the under side of the collar. The parts of the shield are pressed apart laterally by springs lv introduced between them, and they are attached together for convenience of handling by two lscrews fixed in one part, and working in slots in the other part, so that the two parts may slide one past the other.

1 divide the axle-box horizontally into two parts bolted together.

These shields to prevent the entry of dust or the escape of oil from the axlebox are shown in section at Fig. 1, and in dotted lines at Figs. 3 and 4. s and t are the two parts of which the shields are formed, the inner part being pressed up against the under side,

of the collar of the journal by the spring u,

,and the part t resting on the upper part of the collar of the journal. The two parts s and t are pressed apart by the sprin gs at lv c, Fig. 1, so as to fit the recess formed in the axlebox in which they are placed. The parts s and t are attachedto each other by the screws w fw, Figs. 1, 3, and 4, in the manner'showm so that they are free to move vertically for a suitable distance past each other.

I claimv 1. The construction and arrangement of apy paratus for ascertaining whether the axle-box is or is not supplied with oil, consisting of cylinder a, piston b, rod o with knob d, and apertures e eandff, all combined and operating substantially in manner shown and described.

2. The combination, in the car-axle box, of the supply-cock h m, wicks p, carriers o, diaphragm n, oil-cylinder', piston b, and rod c, substantially as set forth. p

3. The dust-shields s and t above and below the journal, respectively, and attached to each other by the screws w, in combination with the spring u acting on the shield s, and the springs v that press the shields apart and against the'i'nner surfaces of their containing recesses, substantially as set forth.
